To cZZ whom it may concern:

Be it known that T, HENRI Fonrr, a citizen of the French Republic,residing at Paris, Department of the Seine, in France, have inventedcertain new and useful Improvements in Carrier-Drive Heads for Lace-Braiding Machines, of which the following is a specification.

The present invention relates generallyto lace braiding machines andmore particularly to a new method of attaching, the driver and thecentre disc to their respective axes, the said members constituting whatis called a braiding quoit or driver in lace braiding machines. Thecentre disc for guiding and controlling the braidingearrier is attachedin such a manner on its fixed axis that it permits of the free passageof the foot of the braiding-carrier so that the periphery of the saidfoot may be tangential to the axis of the head.

Consequently, it will be possible to employ braiding-carriers havingmuch wider footor base portions so that such portions of two adjacentcarriers may touch each other; or on the other hand the present size ofthe feet of the bobbin-carriers may be retained, the distance betweenthe axes of two adjacent heads may be considerably decreased forinstance, a distance substantially equal to the diameter of the foot ofthe carrier.

The resulting advantages are numerous. For example, with the actualspace occupied by a machine it will be easy to add a greater number ofcarriers The path of a carrier is shorter, and consequently there isless wear and more certain working for the withdrawings of the thread;there will be an increase in the number of revolutions of the wholemachine, and therefore a greater outut. V

The cop of the carrier may be larger and greater length of thread. i

The accompanying drawing shows by way of example one constructionaccording to the invention.

1 is a vertical section through a number of braiding quoits with theirrespective carriers, and the Fig. 2 is a plan view thereof, partly insection.

Referring now, more particularly, to the drawing, 1 designates the lowerplate and 2 the upper plate of the machine. These in combination withthe centre discs 3 and 3 respectively constitute the race-way for thebraiding-carriers 4. The vertical spindles 5 and 5 are attached to thelower plate 1, and these spindles together with the pinions 6, sleeves 7and drivers 8 provide the means for driving the braiding carriers. Thedriver 8 and the centre disc 3are in, one piece. elongated lower portionof square cross seotion upon which the sleeve 7 slides freely up anddown accordingto the movements of a jacquard mechanism. The sleeve 7 isprovided with two teeth 7 and with a central groove 7 in which thereengages a control forlg'not shown in the drawing. When the fork is moveddown, the teeth 7 of the sleeve 7, mesh with the teeth 6 of the drivingpinion 6, transmitting the rotary motion of the pinion to the driver 8,that is to say, to the centre discs 3 (see second head Fig. 2).

In consequence of this action there is a crossing of the threads of thetwo carriers placed on the heads.

Tn effecting the foregoing advantages the bolt or screw-head usuallyplaced in the raceway plate 2 is according to the invention sunk in thedriver and therefore shifted to a position below the upper plate 2.

With this object the driver 8 is provided with a recess 9 in which thenut 10 is located and b ting below the plate 2 does not in any mannerinterfere with the feet of the carrier but permits of two adjacentcarriers being arranged much closer together. The two arms 11 whichconnect the driver 8 with the centre disc are cut away for two reasons:.

1st to permit of the insertion and fastening of the nut.

2nd to allow the arms to act as a driver by acting upon the lower disc12 of the foot of the carrier and to serve also as a support for thefoot of an adjacent carrier.

These armsamy extend beyond the centre disc 3 above the race-way plate(Figs. 1 and 2) and operate in the same direction as the lower arms 11.

Owing to this arrangement it is possible to drive the foot of thecarriers at three independent places, namely at the lower disc 12, theupper disc let and the pin 15. The drive will always be effectedcentrally and without amming.

The base of the carrier is the largest which can be made; it consists ofthe disc 14. Each disc may be of such size that two ad- This piece isprovided with an jacent discs can touch each other or slightly; spacedso that they allow sufi ioientplay for the passage of a centralunbraided threadwh'ensuclr isusedi s It will be: th'ens possibleto;zusewlargeriand 1 heavier crops containing more thread, Without itbeing necessary toincrease thespace between the heads.

It is evident that by arranging'the heads close together, .greatadvantages will be at tained Q in the construction of machines.
